GENERAL DESCRIPTION

A double buffered serial data interface offers high speed, three-

wire, DSP and SPI microcontroller compatible inputs using

data in (SDI), clock (CLK) and load strobe (LDA + LDB)

pins. A chip-select (CS) pin simplifies connection of multiple

DAC packages by enabling the clock input when active low.

Additionally, an RS input sets the output to zero scale or to 1/2

scale based on the level applied to the MSB pin. A power

shutdown feature reduces power dissipation to less than 3 µW.

The AD8303 is a complete (includes internal reference) dual,

12-bit, voltage output digital-to-analog converter designed to

operate from a single +3 volt supply. Built using a CBCMOS

process, this monolithic DAC offers the user low cost and ease-

of-use in single-supply +3 volt systems. Operation is guaranteed

over the supply voltage range of +2.7 V to +5.5 V making this

device ideal for battery operated applications.

The 2.0475 V full-scale voltage output is laser-trimmed to

maintain accuracy over the operating temperature range of the

device. The binary input data format provides an easy-to-use

one-half millivolt-per-bit software programmability. The voltage

outputs are capable of sourcing 3 mA.

The AD8303 is specified over the extended industrial (–40°C to

+85°C) temperature range. AD8303s are available in plastic

DIP and low profile 1.75 mm height SO-14 surface mount

packages. For single-channel DAC applications, see the

AD8300 which is offered in the 8-lead DIP and SO-8 packages.
